Default I want to pick some brains

This is mechanical, but not Bonneville. It is G.M. related though.

1992 Chev Silverado 1500 PU

At exactly 60 kph the brake warning lights and ebrake light come on. (on the dash)

Ebrake switch, brake light switch and master cylinder low fluid warning system all check out OK.

Cruise control don't work. Could the two be related? Is there a CC modual that could be causing the problem?


I know I could join yet another forum to ask this question, but I'm here, I'm bored, and you guys and gals are so darn helpful.

So, any ideas?

My guess would be vacc booster or line is leaking.
What about the return spring on the e-brake foot pedal? Those get loose once in a while.

Thanks for the replies, I've checked the vac lines ebrake spring. The fact that the warning lights go on at the same time as the cruise control minimum speed is reached makes me think they are connected in some way.

I'll check out the fulsizechevy forum and see if I can find a solution, I haven't seen that one before. Too many forums to find them all without a referral.

Some cranky people on that forum.

Instead of posting a link to answer my question I got a lengthy post about the use of "search"

Then I found that "search" yielded dick all.

I like the set up of this forum much better. The tech articles are first class. That chev forum could use some lessons from here I think.

Check the sensor(*) that turns off criuse when you step on the brake or ebrake?
I'm not sure if you have it/them but worth looking for.
